HINGE.

Specification of Letters Patent. Patented Aug. 21, 191?.

Application filed December 31, 1913. Serial No. 809,619.

To all whom it may concern.-

Be it known that I, ERNEST J. SWEETLAND, a citizen of the United States, residing in the town of Montclair, county of Essex, and

State of New Jersey, have invented certainnew and useful Improvements in Hinges, of

- which the following is a specification.

My invention relates to a hinge construction, in which the pintle is provided with eccentric portions which are adapted to make the hinge leaves relatively adjustable so as to compensate for wear or for other purposes. adapted for use in connecting the" sections of the casing of -a pressure filter of the general type illustrated and described in my prior Patent No. 1,083,305 of January 6th, 1914:. In that patent I showed a filter comprising two sections hinged at one side, with tension means on both the hinged side and the free side for forcing the two sections together in order to make a tight joint. My present invention has to do with an improved hinge mechanism whereby the tension-locking means is required on only the free side, that is, the side opposite the hinge.

In the accompanying drawings which form a part of this specification, Figure 1 is an end view of a filter provided with my improved hinge and showing the lower movable section of the casing swung out of its normal position to permit the cleaning of the filter; Fig. 2 is a perspective view on an which support the fixed section 3 of the casenlarged scale of the hinge mechanism; Fig. 3 is a transverse sectional view on line IV-IV of Fig. 2, Fig. 4 is a longitudinal view on line VV of Fig. 3. Fig. 5 is a transverse sectional view through the filter.

Referring to the drawings in detail, the numeral 1 designates a base upon which is mounted a pair of standards or uprights 2 ing, being secured thereto by the bolts 4, or in any other suitable manner.

The lower secton by a suitable number of hinges 18 of'the casing is hinged to the upper section. Each hinge comprises an upper leaf 19 securely mounted upon the upper section, and a lower leaf 20 similarly mounted upon the movable section of the casing. wThe upper leafmay be provided with a pair of integral depending lugs 21, beneath which is received. a similar lug 22 forming a part of the lower leaf. The lugs 21 are provided with axially alined central Such a hinge is particularly openings 23, and the lug 22 has a similar circular opening 24. A single shaft'25 extends along the entire length of the filter and acts as a pintle for each set of hinge leaves. This shaft comprises circular portions 26 having a diameter equal to the diameter of the holes through the lugs of the hinges. Between these portions are portions 27 of reduced circular cross-section which are tangent to the periphery of the larger portion of, the; shaft along a single line 28. These portions of reduced diameter are of the same width as the lugs 22 and are so arranged upon the shaft or pintle that they will each come between a pair of lugs 21. As a result, it will be seen that the lower Or movable section of the casing is hung upon the portions of the shaft or pintle of reduced diameter through the medium of the lugs 22 and their associated portions of the hinge, whereas the remainder of the shaftis supported by the lugs 21. One end of the shaft may be provided with a faceted portion 29 for engagement with a wrench to rotate the shaft, and one or more of the lugs 21 may be provided with a set screw 30 passsectionsof the filter casing. Hitherto it has been thought necessary to provide tensioning means at each side of the casing, as illus trated in my prior patent above referred to, since with tensioning means on only one side of the casing and with a hinge of the ordinary type at the other side, there is no way to prevent leakage at the hinged side of the casing, due to wear in the hlnge, and also in the gasket'or packing at that side of the casing. When my improved hinge is used, however, it will be observed that the effective axis of the hinge may be readily shifted owing to the eccentricity of that portion of the shaft or pintle upon which the lower or movable section of the casing is hinged.

Figs. 3 and 4 illustrate the position of the parts when the structure isnew. If, now, there is wear either in the hinge or in the gasket which is adjacent tothe hinge, this wear may be compensated for by rotating the shaft or pintle through a small angle The efl'ect of this rotation will be to raise the axis of the hinge. Sincethe part of the shaft supporting the movable section of the casing 1s eccentric with respect to the main axis of the shaft, that is, the axis about which the shaft as a whole must-rotate, the amount of wear which maybe taken up is equal to the eccentricity or difierence in diameter of the large and reduced sections of the-shaft. This is obviously true since the lug 22 is always hung upon the topmost element-of the reduced portion of the shaft.

Therefore, if the parts are initially in the position shown in Figs. 3 and 4, and wear occurs tendingto cause leakage along the adj acent line of division between the two easing sections, this wear may be taken up by a slight, rotation .of the shaft. If the shaft is rotated through 180 degrees from the positionshown' in Figs. 3 and 4, the result will be that the lower or movable section of the casing is hung from the portion of the shaft section 27 which is tangent to the shaft section of large diameter. In other words, instead of being hung upon-the element 32, as shown in Figs. .3 and 4, thelug 22 will rest upon the element 28,. and the effective axis of the hinge will have been vertically raised a distance equal to-the difference in the diameters'of the two shaft sections. It will be seen that providingthe hinges with a common pintle not only simplifies the construction, but also makes it possible to adfrom the hinges able means for 10 just the parts simultaneously and uniformly. By magking the eccentric portion smaller than the main diameter of the shaft or pintle and causing it to lie within the cylindri-' cal boundary of the latter, there are no out the casing in operative position, suchcas the locking bolts 1llustrated'and described in my prior Patent No. 1,083,305. The general operation 9fv the bolts and camshaft is' described in myprior patent referred to.

While I have illustrated and described only one specific embodiment of my device,

I realize that it is susceptible of wide, variation and I do not desire to be limited to the precise construction shown and described.

Having thus described my invention, I

claim:

1. A hinge including a plurality of pairs of leaves, each pair having circular bearing 7 surfaces capable of being placedin register menses and a continuous pintle including a cylin-' drical member of substantially the same diameter as the bearing surfaces engaging the bearing surface in one leaf of each pair and havin a plurality of eccentric 0rtions of re uced cross section, each of W 'ch supports the second leaf of apair, the eccentric portions lying within the cylindrical boundary of the body of the pintle.

2. A hinge including a leaf comprising two separated sections provided with alined, circular bearing surfaces, a second leaf hav ing a portion adapted to be received between said sections and provided with-a circular bearing surface capable of being placed in register with the bearing surfaces of the'fi'rst leaf, and a pintle including a cylindrical member of substantially the same diameter engaging the. bearing surfaces in the first leaf, and having .a central eccentric portion of reduced cross-section mounted in'the leaf. v

3. A hinge including a leaf comprising two separated sections provided with alined, circular bearing surfaces, a second leaf having a portion adapted to be received between said sections and provided with a circular bearing surface of the other bearing surface capable of being placed in register with the bearing surfaces of the first leaf, a tle including a cylindrical member of su stantially the same diameter engagin the bearing surfaces in the first leaf an having a central eccentric portion bearing surface of the other leaf, and means for preventing the rotation of the pintle with reference to one of the leaves.
